This invention relatesto railway trucks and more particularly to means for mounting journal boxes. within the pedestals of such trucks and is a division of my co-pend- 4 5 ingapplication Serial No. 736,933 filed September 16, 1924;

It is a general objectof the present invenit tion toprovide a, novel and improved form' may be removed from the pedestal while the cushioning means remain in position.

Other and further objects of the invention will become more apparent as the description proceeds, and for a complete, understanding of the invention, reference should be had to the following specification taken in conjunction with the accompanying. drawings,

wherein are disclosed a single exemplary form of the present invention with the understanding, however, that various changes and modifications may be made in the design, arrangement, proportion, shape, size and material of the various parts without departing from the spirit of the invention and the scope of the appended-claims.

and this application aim It .is common practice, in railway car truck construction, to provide on the side frames of the truck, pedestals providing'a sliding mountingfor the journal boxes of the wheel axle. Inorder to insure easier riding, springs are usually inserted between the tops of the journal boxes and the pedest-a1 covers or heads, which springstherefore support .the truck frames, and thus the cars, from the wheels. In the operation, 68 maintenance and repair of these trucks it. often becomes desirable or necessary to replace journal boxes as well as their axles, or

to disassemble these parts for repair and consequently when the side frames carrying to the pedestal legs are lifted from the journal boxes for any cause the springs drop out of position and added difliculty and delay is necessary upon reassembly of the parts. #To avoid these difficulties, to facilitate-the use 7 of several springs having a greater total width than the width of the box, and to insure the proper spacing arrangementfand tensioning of the springs both while the journal boxes are in position and when they 8 are removed, either accidentally, or intentionally, the arrangement of the present invention has been devised.

Referring to the drawings, there is disclosed at 1Q any suitable form of side frame, for instance that described in applicants copending application above noted. Two side frames are necessary for each truck and are connected together by the transoms 11. Each side frame is'provided at either end with a pedestal 12 and may have an intermediate pedestal, as for instance, where used with a Figure l'is a side elevation of a railway" six wheel passenger truck.- Each pedestal comprises inner and outer pedestal legs 13 and 14 respectively and a pedestal cover or head 15, all preferably cast integral with "the side frame as shown. In horizontal cross section the pedestal legs are substantially U-. sshaped, comprising the inner sid or guide face 16 and the side flanges 17, t esections progressively widenin toward the top and the flanges 17 being reinforced at their outer edges by inturned edge flanges 18. The bot- The pedestal covers or heads constitute the tops of substantially rectangular boxlike structures having open bottoms located over the pedestals and formed by extensions from the sides 21 of the side frames, the side covers '22 and the ends 23. For the sake of lightness and to allow for the inspection of the springs over the journal boxes, to be later 4 described, the sides 21 and 22 are provided .and provide flat bearing surfaces29 for a purpose to be later described; The narrow flanges 30 project inwardly a short distance and then vertically upwardly to form the open bottomside of the boxes over the pedestals and serve as a rigid support and brace for the outer legs.

Between each pair of pedestal legs is arranged a journal box 31 of any desiredor conventional type which as is well-known slides between the guide faces 16 of the pedestal legs and has laterally projecting flanges cooperating with the side guide flanges 20 to prevent transverse. movement of the journal boxes in respect to the pedestals. Each'journal box contains a journalbearing 32 adapted to be supported from the .axle 33 and a suitable waste pocket 34 i with lid 35 provided for the supplyv and re- It is found desirable tention of lubricant; to line the guide faces 16 to easily adjust for wear andrfor this purpose there are dis closed liners 36 held in position b having their ri htangled flan es 37 c amped against the bottoms 19 of the pedestal legs by means of the bottom plate 38 bolted to the pedestal legs by means of the bolts 39 and serving-do limit the amount of upward movement of the pedestals in respect to the journal boxes and thus prevent displacement of the boxes from the pedestals.

In the usual practice one or more helical springs concentric with each other are provided between the pedestal head 15 and the top of the journal box, but the number of these springs or nest of springs is necessarily limited by the narrowness of the top of the journal box. In the present construction, however, this difficulty is overcome by providinglthe bar 40 which rests upon the top of the journal box and is preferably positioned thereon by the flanges 41. This bar extends longitudinally of the "side frames and projectsbeyond the guide faces 16 of the pedestal legs as clearly shown in Figure 1 and provides acc mmodation for a' Looaoar larger number of helical springs 42, here shown as three in number, each one being compound, that is, including two or more concentric springs. These springs rest with their lower ends 'on the top of the bar 40 and the top edges of the flanges 41 and are maintained against transverse movement by means of the flanges 30 between which they have a loose fit. They are spaced apart and properly located Within the box over the pedestal by means of the spacing lugs 43, cast integral with the pedestal cover or head 15, and fitting between the respective springs.

By referring to Figure 4 it will be seen that there is an opening 44 beneath the end 23 of'the box containing the springs and above the face 29 of the flange 28 thru which the bar 40 may be inserted longitudinally to assume the position shown in Figure 1.

Therefore, to assemble the device, the springs will be maintained in position by means of the bar resting upon the top ofthe journal box. They are properly spaced from each other by the lugs 43 and are limited in movement transverse to the, truck by the flanges 30 and the narrowness of the top of the box receiving them. They will also remain in position irrespective of the position of the journal box which can be inserted or removed at will, care being taken however, to

see that the bar 40 fits between the lugs 41.

To complete the assembly the bottom plate 38 will be bolted in position.

It will be seen from the above that the construction is well adapted for casting so that the whole pedestal and its associated parts is integral with the side frame, that the various flanges and bridges constitute adequate. reinforcing and strengthening means for all the load carrying parts, that means are provided for inspecting all of the parts without'their removement and that a minimum amount of metal or' labor for its machining is required. The coil springs can be put under any desired initial compression and retained under this compression by means of the bar 40 so that the pedestals are not lifted too far ofl' of the ournal boxes, while at the same time assuring sufiicient spring action so that they will seldom be compressed solid by sudden shocks due to inequalities in the roadbed. If a car is accidentally derailed or if a truck must vbe hoisted for any particular purpose,

the coil springs over the journal boxes will always remain in position even tho the journal boxes are removed from the pedestals.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
